SANHA transitional press fitting for gas, 18 mm x 3/4" — coupling, model 1112701834

SANHA transitional press fitting for gas, 18 mm x 3/4" — coupling, model 1112701834 is a mechanical transition component designed to join 18 mm press copper or stainless-steel tubing to a 3/4" threaded gas connection. The fitting provides a press-side connection compatible with standard 18 mm press systems and a tapered 3/4" threaded interface suitable for attaching valves, regulators, or appliances in domestic and light commercial gas installations. The component is intended for use in gas distribution lines where a reliable press-to-thread joint is required.

Advantages

The fitting enables a quick, tool-assisted press connection that reduces installation time compared with soldering or welding and minimizes hot-work risks. The press interface creates a leak-resistant mechanical joint when used with the appropriate press tools and profiles, while the threaded 3/4" end provides a conventional and serviceable interface for downstream components. The compact brass construction offers corrosion resistance and dimensional stability under normal gas service conditions.

Suitable for

• Connecting 18 mm press copper or stainless pipe to 3/4" threaded gas valves and regulators
• Domestic natural gas and LPG distribution lines in residential buildings
• Light commercial gas installations requiring press-to-thread transitions
• Retrofit work where existing threaded appliances or fittings must be connected to press piping

Key specifications

• Press connection diameter: 18 mm compatible with standard 18 mm press systems
• Threaded connection: 3/4" tapered thread suitable for gas fittings
• Material: brass body with press-compatible sealing element (factory-installed)
• Application medium: natural gas and LPG (where locally permitted)
• Intended use: mechanical press-to-thread transition in gas distribution lines

How to use

Cut and deburr the pipe to the correct length, then insert the 18 mm copper or stainless pipe fully into the press connection until it seats against the shoulder. Use the specified press tool and compatible jaw/profile to perform the press operation according to the tool and fitting manufacturer instructions. After pressing, verify the mechanical joint visually and, where required by local code, perform a pressure/leak test on the gas system. Thread the 3/4" end to the required valve or appliance using appropriate thread sealant or tape approved for gas applications, and torque to the manufacturer's recommended values.

Usage recommendations

Use only press tools, jaws/profiles, and sealing elements that are approved for SANHA press fittings and comply with local gas installation codes. Follow all applicable regulations and perform pressure and leak tests after installation. Do not use the fitting for fuel oil, water heating, or other media unless explicitly approved by SANHA and local standards.
